"On the sets of Johnny Gaddaar I learned many things from (director) Sriram Raghavan, which I remember on the sets of all my movies and try to imbibe them," he added.
In Johnny Gaddaar Neil played Vikram, one of the five members of a gang that runs a gambling club and conduct other underhand deals. The film earned him a Filmfare best male debut nomination.
Neil's 3G is a horror-thriller. He says while shooting some scenes, he was reminded of Johnny Gaddar.
"There was a time when I remembered Johnny Gaddar. There the character was doing everything but feigned innocence. Similarly, Sam (his 3G character) has also used vulnerability, but in a different way," he said.
3G, which has been co-directed by Sheershak Anand and Shantanu Ray Chhibber, is set for March 15 release and it will see Neil romancing Sonal Chauhan.
